GASOLINE PUMP.

Application filed November 19, 1924. Serial No. 750,887.

Our invention relates to pumps adapted for use with gasoline or othermotor-'tuels, vtor delivering the liquid Jfrom a buried container to thefuel-tanks oi' motor vehicles.

1 1t is the object otl our invention to provide a simple, durable andinexpensive pump ot' this class, especially adapted for use by 'farmersand other consumers of moderate quantities of motor-'tuch among whom itis l desirable that gasoline be bought in barrellots, then stored insuch a manner as to avoid lire-hazards, and dispensed `from the storagecontainer to the vehicle-tanks as needed. A particular object of ourinvention is to provide means by which the dispensing ot the motor-fuelunder the conditions above noted may be elliected with a minimum ofwaste by leakage, spilling or evaporation, and by which the drawing ofSe the iuel from the storage container may be prevented except by anauthorized person.

A further object is to provide simple and etlective means for regulatingthe quantity ot liquid to be delivered at each stroke ol the pump.

In the accompanying drawings Fig. 1 1s a` vertical section of a pumpembodying our invention, Fig. 2 is a detail axial section or' thepump-cylinder, Fig. 3 is a detail transi'e verse section on the line 3-3of Fig. 1, and F ig. 4: is a transverse section o'l the cylinder on theline 4-4 oi Fig. l.

Our pump is intended principally to be used in connection with the metaldrums or barrels in which gasoline is commonly sold, and whichconstitute substantially the minimum wholesale quantity in which thefuel may be bought. The quantity of inflammable material contained insuch a barrel is too large to permit storage thereof in a buildingwithout causing an excessive lirehazard, and it is our intention,therefore, to utilize one ot the metal barrels as a permanent containeror storage tank, by placing the saine underground, connecting the pumptherewith so that the contents may be withdrawn as required. andrefilling the barrel from time to time through the return, overtlow ordrainage conduit of the pump. 1n Fig. 1 the barrel 5 is represented asdisposed underground, and the pump-body is connected therewith by meansof the return-pipe 6, of which the lower end is screwed into the head ofthe barrel, and the upper end is screwed into the base 7 of the lilpump. The lower head S of the pump-cylinder is formed integrally withthe upper portion of said base 7, and the latter is hollow or Chamb-eredto provide a continuation oit' the passage through the pipe G. At oneside ot and integral with the chambered base 7 is a tubular arm 9 ofwhich the lower portion extends diagonally upward and is connected withthe base by an integral web or flange 10, and the upper portion extendsvertically, there being an enlarged head 12 at the upper end ot thevertical portion, and the opening through said head having therein anannular recess ior receiving a packing or gasket1ing 11. the head 12 isan integral laterally extending lug 13 having a vertical opening 14therein.

The head S is annularly groovcd to receive the lower end et thepump-cylinder 15, which is formed by a section of smooth-tinished pipeor drawn tubing. the head having a plurality of laterally extending lugsfor receiving the tie-bolts 1G, and said bolts passingthrough similarlugs on the upper head 17. Said head 17 is annularly recessed to receivethe upper end of the cylinder 15, which is clamped between the heads bythe tie-bolts 16, suitable gaskets 18 being provided, whereby to formfluid-tight joints at both ends of the cylinder. At the center of thehead 17 is a packing-gland 19 through which the pistoni-od 2() passes.At one side of the head 17, formed integrally therewith and extendingupwardly therefrom, is the tubular standard 21, into which at its upperend is screwed the delivery pipe 22. Said pipe 22 is extended up to a.suitable height, and the upper portion is formed into a return-bend 23,to which is connected the hose or flexible conduit 24. At the end of thehose is a nozzle 25 having a slightly tapered port-ion which is adaptedto tit within the gasket-ring 11 to `form a tight joint with the head 12of the return-tube 9, when the nozzle is inserted therein as shown inFig. 1. r1`he nozzle also has a laterally extending flange 2G vwith anopening 27 therein adapted to register with the opening 14 of the lug 13on the head 12, whereby a padlock 28 or similar fastening means may beapplied to prevent removal of the nozzle from the socket or mouth ot'the return-tube.

To the upper end of the piston-rod 2O is secured the rack-bar 29 whichextends up be- At one side of tween the guide-lugs 30 :formed integrallywith and extending laterally from the tubular standard 2l. In the outer`portions of said lugs is liournaled` a shaft 3l, the same being :termedintegrally with a crank 3Q, and upon said shaft between the lugs is secured the pinion S3 which meshes operatively with the teeth of therack-bar 29. At the upper end ot the racltbar is a lug Sil which extendslaterally above the upper end et the standard 21, whereby to engage thesame as a stop to limit the downward movement ol the rack-bar andpiston-rod. A stop tor similarly limiting` the upward niioven'ient ot'the rack-bar is secured adjustably upon the pipe 22, said stopcomprising a pair of matingrmembers 35 having portions which lit aboutthe pipe and are clamped thereon by means oft bolts 86 extendedtransversely through them.

rlhe lower portion of the piston-rod Q0 passes slidably through thepiston 3T, and upon thelower end ot the rod is lixedly se- Cured thevalve 38. The piston has the usual cup 39 oit pliable material arrangedto torni a fluid-tight packing against the walls of the cylinder.Downward movement ot the piston-rod relative to the piston is limited bya transverse pin L l0 extending through the rod above the pieton, andupward movement of the rod relative to the piston is limited by theengagement ot the valve 3S with its seat, which is formed on the. lowerside ol2 the piston. The valve 38 is thus positively actuated by thepistonrod, being closed at the beginning of each upward movement ot therod,r and being opened at the beginningot each downward movemennthepiston being actuated only after the valve has been closed or opened, asthe case maybe.

The supply or suction-pipe al is screwed into a central opening in thelower cylinder-head 8, said pipe 4l extending down through thereturn-pipe ti into the barrel or tank 5, and terminating near. thebottom thereof. `At the lower end o'tf the suctionpipe a check-valve issecured thereon, said valve"` comprising a body-portion 42 having at thelower portion thereot a seat Ytor the valve-ball l the body 4l2beingscrewed on the end of the pipe, and a spring 44 being` arranged betweenthe end ot the pipe and the ball, to press the latter' toward its seat.

The operation ofthe pump will be obvious. Owing to the positiveoperation of the piston-valve, primingraoi the `pump is unnecessary,-a-sv'a'nyair in the suction-pipe,

nelaeae or in the cylinder below the piston, will be discharged `by oneor two strokes oit the piston, which is actuated reciprocatingly byturning the crank 82 in alternating directions. dWhen the fuel from thestorage container is to be withdrawn, the hose-noa zle` 25 is removedfrom the socket at the mouth of the return-tube, and after the pump hasbeen operated to withdraw the desired amount of 'fuel the nozzle isreplaced in the socket, so that loss by leakage trom the hose, orevaporation through the returnpipe, is entirely prevented. When thehosenozzle is in place inthe socket, operation of the pump would merelycirculate a portion ot the liquid trom the barrel 5 through the pump,hose and return-pipe. ltelilling ol' the storage container is readilyeltected through the return-pipe, after removal of the hose-nozzle fromthe socket at the mouth thereof. lt' it is desired to measure the tueldelivered by the pump, the stop tor limiting upward movement of therack-bar may be so adjusted that each iull stroke o't the piston willdeliver a determined quantity of the. liquid, and, consequently, a counto'l the number of strokes made will accurately indicate the volume ot'liquid discharged.

lt will be particularly noted that by the described construction we areenabled to provide an eliicient and durable pump o'l' this class at avery moderate cost, the sims plicity ol' structure being attained partlyby combining as an integral unit the lower cylinder-head, the base, andthe return-tube; and also by combining the upper cylinderhead witlithetubular standard to form a support for the d,eliverypipe and for therack-bar guides.

Now, having` described our invention, what we claim and desire to secureby Letters Patent is;

ln a structure of the class described. a storage container, a pump, asuction-pipe connectedwith the pump and extending into the contain-er, a'flexible discharge conduit connect-ed with the pump, a nozzle arrangedat the end ot said discharge conduit, a re` turn-tube connected with thecontainer, means forming a socket at the mouth ot said return-tube forreceivingl the nozzle and forming a detachable fluid-tight connectiontherewith, and registeringmeans on the socketv andy nozzle adapted toreceive a lock for retaining said parts in fluid-tight connection.
